[Bldg-sim] Recommended reading on comparison of models to actual?

Tue Jun 18 13:14:39 PDT 2013

Jeremiah,

That is an important topic among researchers and practitioners in the
simulation community for the last 20-30 years.

I made a presentation on this topic in a public EETD/LBNL seminar, A closer
look at the energy performance of buildings: simulated vs. measured. Slides
are available in PDF at
http://eetd.lbl.gov/news/events/2011/03/03/a-closer-look-at-the-energy-performance-of-buildings-simulated-vs-measured

I have some journal articles discussing related topics. You can find them
by using the Google Scholar.
